Normally to get optimum results from the solar panel the minimum voltage output from the panel should be higher than the required battery charging voltage meaning even during adverse conditions when the sun rays are not sharp or optimum the solar panel still should be able to generate a voltage more than say 12 volts which may be the battery.
Solar panel output voltage regulator.
The panel voltage drops about 0 4 per c and the power by about 0 5 per c.
This product the zeallife solar panels charge controller is great for those regulating the voltage from a 12 volt solar panel to a safe level for charging 12 volt batteries.
It regulates the voltage and current coming from the solar panels going to the battery.

The stc we mentioned before measures the panel output at 25 c and any increase above that is going to drop the voltage and power output of.

Solar panels and temperature.
The solar charge regulator features three led indicators high voltage low voltage charging and three connections for the solar panel keyed two pin connector battery keyed two pin connector and 12v output 3 in.
This solar charge regulator protects and regulates the charge of a 12 volt storage battery using solar panels.
Something however that does make a difference especially to us in australia is temperature.
Most 12 volt panels put out about 16 to 20 volts so if there is no regulation the batteries will be damaged from overcharging.
